Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42436, here are decompositions:
- 3 + 42433 = 42436
- 29 + 42407 = 42436
- 113 + 42323 = 42436
- 137 + 42299 = 42436
- 179 + 42257 = 42436
- 197 + 42239 = 42436
- 227 + 42209 = 42436
- 239 + 42197 = 42436
Showing the first eight; more decompositions exist.
